Definitions

  • the present invention relates to an arrangement and a method for assigning connection points of an electrical installation to the safety circuits of the electrical installation, the arrangement comprising two of the more measuring devices, each of which has connection means for connecting the respective measuring device to one of the connection points and transmitting means.
  • the three-phase supply network voltage, or mains voltage for short, arriving at the building connection point is first routed to a central distribution box and from there further distributed to the building's individual supply circuits.
  • Each of these supply circuits is protected from overload by at least one fuse, which is why they can also be referred to as fuse circuits.
  • the fuse circuits each supply one or more connection points at which electrical consumers can be connected to the electrical installation. Connection points are, for example, sockets, or usually via switches, guided lamp bases or connection points for directly connecting, usually stationary, consumers.
  • connection point The distribution of the individual connection points to the fuse circuit as well as the division of the fuse circuits to the phases of the supply voltage is carried out by the electrician when the electrical installation is created. This assignment is often not documented or not documented sufficiently. Even if documentation, ie which connection point has been assigned to which fuse and which phase, has been created, it is often lost or becomes outdated over time when changes are made to the electrical installation.
  • the US patent application US 2016/0274174 A1 discloses a more complex solution to the fuse allocation problem, which includes several modules connected to the connection points of interest, each of which has its own ID in the form of a not too large natural number. After plugging in or switching the mains voltage back on by pressing the fuse, each module counts the zero crossings of the voltage at its connection point and the module that is the first to reach its ID number becomes active and begins to send its ID via the external conductor of the electrical installation, so that the signal can be received at the fuse box or at another connection point on the same fuse circuit. Specifically, it is recommended to pick up the signal using a handheld device on the fuse box.
  • the Patent US 9,552,446B2 presents a comprehensive solution to the fuse circuit mapping problem in which a user first uses a computer program to create a virtual representation of the fuse box and a building/floor plan on which the connection points are marked and then connects modules to the connection points, with the ID of the respective module on which is included in the building/floor plan. Then, using a probe connected to a computer, probe each circuit in turn A signal is fed in which is recorded by the connected modules and used to determine information about the fuse circuit. This method also requires access to the fuse box and sequential switching of the fuses.
  • the patent specification US 8,018,219 B2 presents a system consisting of two or more modules, which is more suitable than the systems presented so far for the task of deciding for two or more connection points of interest whether they belong to the same or different security circuits, which is reduced compared to a full security assignment.
  • the modules are plugged into the sockets of interest. After a user input on one of the modules, it feeds a voltage or frequency modulated signal generated by a signal generator on the module into the socket into which it is plugged. All modules that receive this signal indicate this using display means on their front. With this system, membership of the same or different safety circuits can only be clearly determined if the safety circuits are electrically separated from each other.
  • the present invention has set itself the task of finding an improved arrangement for carrying out an assignment of connection points to fuse circuits of an electrical installation, which overcomes the disadvantages described above with simple and uncomplicated handling and, in particular, can be used even during operation without access to the fuse box.
  • the arrangement includes at least two, preferably more, in particular three, four or five, measuring devices, each of which has connection means to a connection point of the electrical installation, load test means including voltage and current measuring means for carrying out a load test and recording the voltage values measured in the process Voltage present at the connection point as well as a current flowing through the connection point and data exchange or transmission means in order to exchange the measurement results with other measuring devices or another device, for example a central control or monitoring device.
  • the arrangement also includes at least one device which is equipped with evaluation means for evaluating the voltage and current measurements obtained during the load tests, this evaluation at least carrying out the desired assignment of the connection points to a fuse circuit of the electrical installation.
  • this assignment can be understood as a specific assignment of the connection point to a specific fuse identified in the fuse box, but assignment means a relative assignment in which the user of the arrangement has a Receives feedback as to which of the connection points of interest measured using the arrangement are in the same fuse circuit and which are in different fuse circuits. This information is sufficient for the application scenarios considered at the beginning, in which connection points are sought in various safety circuits for connecting powerful consumers.
  • the evaluation device equipped with the evaluation means also has display means with which the user can see the evaluation results, including, in particular, the determined fuse circuit assignment of the measured connection points.
  • the evaluation device also has at least means for receiving the measurement data sent by the measuring devices. In addition, it can also be equipped with data transmission means to pass on control commands or other information to the measuring devices.
  • the evaluation or control device can be a separate device from the arrangement, for example a portable device that communicates with the measuring devices via radio. Alternatively, this can be one of the measuring devices, which in addition to the evaluation and display means also has the connection means for connecting to a connection point and the load test means.
  • all measuring devices are designed in the same way, that is, they all have Evaluation and display means, and which serves as a control device is determined by the device from which the user makes his entries.
  • the stress test schedule includes a list of measurement time windows, each of which is assigned to a measurement device.
  • a measurement time window is defined by a start time and a duration or a start time and an end time.
  • the times can be in the form of usual ones time units, i.e. H seconds or milliseconds, or they are given in the form of a number of zero passes of the alternating voltage present at the connection point.
  • the load test schedule can be communicated to all measuring devices or each of the measuring devices can only receive information about the measurement time windows assigned to it.
  • the measuring devices then carry out stress tests according to the measurement schedule and record the voltage and current values determined.
  • a measuring device switches a defined test load to the connection point for the duration of the measurement time window and measures the current flowing as well as the voltage at the connection point resulting from this current.
  • This voltage will have a voltage drop ⁇ U compared to the voltage with an open circuit/infinite load, i.e. outside of the load test.
  • this voltage drop ⁇ U can also be recorded.
  • Both the measured voltage and the voltage drop ⁇ U are not only measured at a certain point in time, for example in the middle, during a time window of a load test of the time window, measured and recorded, but rather the course of the voltage or voltage drop is determined during the entire time window. This can be done by dividing the time window into a fine time grid and recording a measured value or a pair of measured values at each point in the grid. Alternatively, or when post-processing the raw data recorded as described above, the amount of data recorded in a time window can also be reduced by only recording significant changes in the measured values together with the time at which they occurred. Here, as in the following, significant means a change that exceeds a certain accuracy or precision of the respective size.
  • the measuring device can record voltage values or voltage drop values with an accuracy of plus or minus 10 millivolts, then all voltage changes greater than ten millivolts are significant.
  • the significance threshold used for the prescribed post-processing or measurement data reduction can be chosen to be equal to the intrinsic measurement accuracy of the voltage or current measuring device used, but can also differ from this and have a larger value, for example 2, 3, 4 or 10 times larger .
  • the voltage measured at the connection points is an alternating voltage, which is why the instantaneous voltage value changes (periodically) during the measurement time window.
  • it is not the voltage signal that changes periodically that is recorded, but rather only measured values at certain phase angles, such as 90° and/or 270°, corresponding to the extreme values of the voltage.
  • the measurement result of the measurement time window is then averaged over the recorded voltage or Voltage drop readings. This averaging can also be done intrinsically by using a sufficiently slow voltage measuring device.
  • the evaluation means determine the desired fuse circuit assignment and, in some advantageous embodiments, also further information about the electrical installation and the measured connection points.
  • the evaluation means divides the stress test period into time periods, with one section being characterized by the measuring device carrying out a stress test in this time period. For example, a measuring device can first begin its load test at a first connection point, which lasts a total of 100 milliseconds lasts, and after 50 milliseconds have passed, another measuring device at a second connection point also begins a stress test of the same total duration.
  • the time windows of the two measuring devices at the first and second connection points are then divided into three sections, each lasting fifty milliseconds: a first section in which only the first measuring device carries out a load test, a second section in which both the first and the second carry out a load test at the same time, and a third section in which the first measuring device has already completed its load test, but the second one continues to carry out a load test.
  • the number of time periods to be considered expands to five : a first of 50 milliseconds in which only the first measuring device is active, a second, subsequent one of 25 milliseconds, in which the first and second measuring devices carry out load tests at their respective connection points, a third, subsequent one of also 25 milliseconds, in which all three measuring devices are active at the same time, a fourth of 50 milliseconds in which the second and third measuring devices carry out stress tests at the same time and a fifth and final one of 25 milliseconds in which only the third measuring device is active.
  • the evaluation is carried out in such a way that the evaluation means or means compare for each time period which voltage drop occurred at the individual connection points and link this information with that which is active in this time period, i.e. H. measuring devices carrying out a stress test. All connection points that have a significant, i.e. H. have a voltage drop within the specified accuracy that is different from zero or above a predetermined or user-selected significance threshold, assigned to the same connection points, as the connection point of the measuring device that is active at that time.
  • the fuse circuit assignment does not only take place after a qualitative linking consideration of the measured voltage drop values, but line resistances of pairs, triples, etc. are determined for each time period from the data available for this time period using the current measurement values that were also recorded, generally for all subsets of the connection points involved.
  • the common line resistance represents the resistance in the supply lines of the electrical installation leading to the connection point through common line sections, i.e. H. Line sections through which a current flowing from the fuse box to the respective connection points must in any case pass through on the way to each of the connection points included in the subset under consideration.
  • the common line resistance is therefore a measure of how far or how close behind the fuse box the supply line branches to the various connection points of the subset under consideration.
  • a comparatively high common line resistance indicates that this branching point is quite far behind the fuse box, and therefore there is a comparatively long common supply line to the connection points.
  • a low common indicates Cable resistance indicates that the branching takes place quite early behind the fuse box.
  • connection points to safety circuits are now carried out according to the second method based on the common line resistances determined for each load test period in such a way that the set of disjoint subsets of connection points comprising all connection points is selected as the assignment in which the minimum, one of the subsets of the Quantity associated common line resistance is maximum.
  • a subset of a set under consideration has a common line resistance of 0 for all connection points it contains, it is incorrectly assigned to at least one of the connection points, i.e. H is in another fuse circuit.
  • H is in another fuse circuit.
  • the present invention therefore proposes, in preferred embodiments, to carry out a (further) stress test measurement run either from the beginning or when a certain criterion is present, in which measurement time windows overlap. In this case, two or more of the measuring devices are active at the same time during the overlap section.
  • connection points For the assignment to the safety circuits, it is then decided whether or which of the connection points show a significant jump in voltage drop in the overlap period compared to the periods in which only one of the measuring devices is active. If there is at least a short, common line section, such a jump is to be expected at connection points in the same fuse circuit, since the current flowing to the other connection points in this fuse circuit, which simultaneously carry out a load test, must also flow via this common line section and thus to The other connection point leads to a voltage drop which, when using the same test load for both active connection points, is essentially approximately twice the voltage drop in the case of activity of only one measuring device. However, not only non-active connection points show that they belong to the same safety circuit Like the connection points of simultaneously active measuring devices, there is an increased voltage drop, but this also applies to the connection points of active measuring devices themselves.
  • the arrangement according to the invention are therefore preferably further prepared to assign two connection points which have a higher voltage drop in a simultaneous load test of the measuring devices connected to them than in the respective individual tests to the same fuse circuit.
  • the evaluation means can be prepared to assign a connection point that, during a simultaneous load test of two or more other connection points belonging to the same safety circuit, to the same safety circuit as these two or more other connection points.
  • the result of the evaluation is presented to the user by the evaluation device d. H. a central control device or one of the measuring devices.
  • connection points of interest In the simplest case of only two connection points of interest, an arrangement of two measuring devices is used, each of which is connected to one of the connection points.
  • start criterion which can be set by connecting itself or by operating a corresponding control element on one of the measuring devices or a control device
  • a load test schedule is created by the coordination means of the measuring devices or the control device, which has a test time window for each of the measuring devices. These test time windows can be disjoint or overlapping.
  • the measuring devices then carry out stress tests according to the schedule.
  • the measurement results for the voltage and current values at the connection points are sent to the evaluation unit over the course of the measurement cycle.
  • connection points are assigned to the same fuse circuit if the connection point of the non-active measuring device shows a significant voltage drop during the load test of the other measuring device.
  • this is referred to as a mutual significant voltage drop.
  • the evaluation unit works with a significance threshold of 100 mV when evaluating the load test measurement results, above which there is a potentially significant voltage drop, then a second, higher significance threshold can be defined, for example 200 mV. If a voltage drop is measured between the first and second significance thresholds, i.e. between 100 and 200 mV in the aforementioned example, the evaluation unit can decide to carry out a further stress test with overlapping test time windows in order to reduce the remaining uncertainty regarding the correct assignment.
  • the second measurement process with simultaneous load test measurement shows no additional voltage drop at both connection points, i.e. no increased voltage drop compared to the first measurement, it is decided that the two connection points are in different fuse circuits lay.
  • the opposite evaluation result follows: the two connection points must be in the same fuse circuit.
  • the arrangement according to the invention makes it possible for the user to find the assignment of two or more connection points to the fuse circuits of the electrical installation, for example of a building or ship, in a simple and intuitive manner, without requiring access to the fuse box and also without the ongoing operation of the connected devices.
  • the load switched to the connection points during the load test is chosen to be sufficiently high to almost rule out overloading the fuse.
  • the load is preferably between 20 and 2000, particularly preferably between 100 and 200 ohms.
  • a safety circuit assignment for all connection points of the electrical installation is possible by a single worker or user in a short time and without any additional aids.
  • connection means or means is a plug, for example the Euro or Type F Schuko plugs commonly used in Germany.
  • the connection means can also be a thread that can be screwed into a lamp holder or a few connection terminals, for example alligator clips.
  • the measuring devices can each have a single connection means, or in further preferred embodiments, different connection means.
  • the connection means are particularly preferably designed to be interchangeable, so that a measuring device can be prepared on site depending on the intended use and the connection point to be measured.
  • the load test means of the measuring devices of the arrangement according to the invention comprise a controllable load in the form of an electronic or electrical switch, for example a transistor, thyristor, a bidirectional thyristor diode (TRIAC) or a relay.
  • a control unit of the measuring device monitors the time that has elapsed since a start criterion occurred and switches the controllable load to the connection point at the right time to begin the load test. When the end time is reached or the duration of the load test of this connection point specified by the load test schedule has expired, the switch is deactivated again and the load test is ended.
  • the coordination means of the arrangement according to the invention enable the creation of load test schedules, with at least one measurement time window being assigned to each connection point involved, at least in a first measurement run. In subsequent measurement runs, a measurement time window can also be assigned to only a part, in the minimum case only one, of the connection points.
  • the coordination means can either be housed in a central control device, which, after activation, sends a request for accessible measuring devices via a transceiver and registers all responding measuring devices in a measuring device list.
  • the list can be updated periodically to remove measuring devices that are switched off or disconnected from the respective termination point so that they are no longer taken into account in future stress tests. This avoids a time window being assigned to measuring devices that are no longer active in a load test schedule.
  • coordination means can also be integrated into each of the measuring devices and one of the measuring devices is selected as a control device.
  • the coordination means can also be implemented distributed across the measuring devices using peer-to-peer coordination mechanisms.

  • the transceiver of the measuring devices, as well as the transceiver of the control unit, if available, can work wired.
  • the wired data exchange preferably takes place via the outer conductor of the electrical installation itself. This means that the transceivers feed a signal encoding the corresponding data directly into the outer conductor of the electrical installation.
  • a successful data exchange requires that all data backup circuits to be measured remain electrically connected to one another. In such an embodiment, the fuses in the fuse box must not be switched off.
  • the transceiver of the measuring devices and possibly the control devices is a wireless transceiver that enables data exchange using a suitable protocol, for example the Wifi or Bluetooth protocol.

If it has been verified that all measuring devices were based on the same measurement data for the evaluation, a new evaluation is initiated and the measuring devices are compared again.
  • Connecting a measuring device to a connection point, switching on a control device, if available, or a user input on one of the measuring devices or a control device can serve as a starting criterion for the start of a measurement run.

  • a recommendation for the maximum power that should not be exceeded at this connection point is determined by the arrangement, more precisely the evaluation means of the control device 1.C, based on the current and voltage values measured during the load tests and the parameters of the electrical installation 3 and the connection points 30.1 determined from them - 4, such as the line resistances of the common lines and internal resistances of the connection points. This recommendation can be shown to the user on the display 25 of the control device 1.C in the form of a performance value.

  • connection means for connecting to a connection point
  • load test means for load tests.
  • the functioning of the arrangement is particularly preferably not dependent on the control device 1.C actually being connected to one of the connection points of interest to be measured.
  • the control device can also be operated in a simple control and display role. In other embodiments, it does not have connection or load testing means and is always limited to pure control and display functionality.
  • connection means 21 preferably include a cable 212, at the end of which the actual connecting piece, for example a plug, is attached.
  • the Fig. 2B shows measuring device 1.M, also called measuring adapter, which is in Fig. 1 schematically illustrated arrangement according to the invention 1.
  • the front of the cuboid housing 20 includes, with the exception of the display 25, the same display LEDs 24 as the control device 1.C for displaying the quality of the radio connection, the result of a protective conductor test and a resilience test.

  • FIGS 3A - 3C and 4A - 4D an embodiment of the fuse circuit assignment method according to the invention is illustrated. This method can be carried out using the arrangement according to the invention, for example an arrangement as described above Figures 1, 2A and 2B illustrated, executed.
  • Fig. 3A shows schematically an electrical installation 3 with a house connection 31, in which the phases L1, L2, L3 of a supply voltage from an external supply network (not shown here) are transferred to the (internal) electrical installation 3.
  • the phases are passed on to an exemplary distribution node 32.
  • Distribution nodes 32 There can also be several such distribution nodes 32, for example a main distributor and several downstream sub-distributors.
  • the conductors coming from the house connection 31 branch out and are fed to several fuses 3.A - E.
  • fuses 3.A, 3.B and 3.C are assigned to phase L1
  • fuses 3.D and 3.E are assigned to phase L2.
  • no fuse associated with phase L3 is shown for simplicity.
  • each of the phases L1 - L3 has at least one assigned fuse, since the power requirement of the consumption supplied via the electrical installation 3 should be distributed as evenly as possible among the three phases for reasons of supply network stability.
  • the connection of the neutral conductor N and the protective conductor is shown PE dispensed with. Experts are familiar with the fact that and how the connection points must be connected to them via the electrical installation. External conductors lead from the distribution node 32 to several, here for example six, connection points 30.1 - 6, such as sockets, lamp holders, switches or connection points for directly connecting immobile or at least very rarely moved consumers.
  • a schematically indicated measuring device 1.M of the arrangement 1 according to the invention is connected to each of the six connection points 30.1 - 6.
  • the coordination means of the arrangement which can be implemented as a central control unit of one of the measuring devices acting as a control device or also distributed using a cooperative control of the measuring devices 1.M, create a load test schedule LTS1. In the embodiment of the method according to the invention presented here, this is by default a schedule in which each of the six measuring devices is assigned one of six immediately consecutive time windows, each time window having a duration T.
  • T The duration T must be sufficiently long to contain at least a maximum value of the alternating voltage present at the connection point. With the 50 Hz voltage commonly used in Germany, each voltage period lasts 20ms. Accordingly, T must be at least 10 ms in order to include at least a voltage maximum or minimum in the measurement. However, T is preferably longer in order to include several extreme voltage values in the measurement and thus increase the measurement accuracy. For example, T can include one, two, three, five or even ten voltage periods and therefore, at 50 Hz AC voltage, 20, 40, 60, 100 or 200 ms, or at 60 Hz AC voltage, 16.7 ms, 33.3 ms, 50.0 ms, 83.3 ms or 166.7 ms.
  • the drop in the voltage measured at the connection point under load is caused by the resistance or generally the impedance of the cables leading to the respective connection point as well as the internal resistance of the connection points themselves.
  • Fig. 3A These are shown as an example for the three connection points 30.1 - 3 located in the fuse circuit of fuse 3.A.
  • the part of the supply line from the fuse 3.A that is common to all connection points 30.1 - 3 has a resistor R123 and the part that is common to all connection points 30.1, the connection points 30.2 and 30.3 has a resistor R23.
  • the resistors R1, R2 and R3 describe the resistances/impedances, which can only be assigned to the respective connection point 30.1, 30.2 or 30.3, ie they are the sum of the line and internal resistances.
  • FIG. 3B and 3C This is illustrated as an example for an arrangement 1 with six measuring devices connected to the six connection points 30.1 - 6.
  • the Figure 3B shows an example of qualitatively expected time curves of the voltage drops ⁇ U n connection point 30.n during the time interval [0, 6T], which corresponds to the total duration of the in Fig. 3A LTS1 stress test schedule shown.
  • the solid lines correspond to the values of the (sinusoidal) alternating voltage present at the respective connection point averaged for the measurement time window.
  • the voltages at the phase angles 90° and 270° which correspond to the extreme values of the voltage, can be recorded and averaged explicitly, i.e. mathematically.
  • a voltage measurement is carried out with a slower voltage measuring device in which the averaging takes place inherently.
  • an averaging according to the first method is indicated continuously in the form of crosses for the uppermost voltage curve ⁇ U 1 of the connection point 30.1 and for selected time periods of other measuring points, with each cross corresponding to a measured voltage drop value.
  • the relative deviation of the individual measured values from the mean is shown exaggeratedly for better visibility. In practice, only small fluctuations in the measurement accuracy would be expected. The exception to this are changes in the operating state of other consumers supplied by the electrical installation 3, not shown here, when measuring during operation, which also cause voltage fluctuations. If the fluctuations caused by this last for a significant fraction of the time window length T, with explicit averaging this can be recognized at the latest during the evaluation based on a systematic deviation of the individual measured values and the stress test can be repeated. Alternatively, a measuring device 1.M can also detect such fluctuations and systematic deviations during the load test and inform the other measuring devices and/or the control measuring device of this, whereupon the test can be aborted and restarted after a new stable state has been established.
  • the type of averaging is not crucial for the present invention. The only important thing is the accuracy and precision of the measurement.
  • only one of the measuring devices 1.M can take over the function of a central control device, create the load test schedule and simply inform the other measuring devices of their respective measuring time window. They would then only have certainty regarding their own measured values, but would not be able to carry out a complete evaluation.
  • the measurement results are passed on from the other measuring devices 1.M to the measuring device 1.M that takes over the control function, which combines the results and carries out the evaluation.
  • connection points 30.1 - 6 show the largest voltage drop during the load test of the measuring device 1.M connected to them, since the largest series resistance comes into effect here, which is the sum of any common line resistances (connection points 30.1-3) and in each case the individual ones Resistors correspond.
  • the voltage drop values of one connection point during load tests of the other connection points are crucial for the fuse circuit assignment sought according to the invention.
  • the voltage drop values of the group of three connection points 30.1 - 3 show a significant voltage drop even during load tests of one of the other connection points in this group. This shows that there are quite large common line resistances R123, R23. Since the total common line resistance for the two connection points 30.2 and 30.3 corresponds to the sum of R123 and R23, the voltage drop is at one of these two connection points higher during the load test of the other than during the load test of the third connection point 30.1 of the group of three. This is due to the voltage drop curve diagrams Fig.
  • connection points 30.4 - 6 show no significant voltage drop during load tests of the connection points 30.1 - 3 (see, for example, the top three arrow diagrams of Fig. 3C ).
  • connection points 30.1 - 3 are assigned to a safety circuit, which in Fig. 3B by which the dashed box S1 comprising three connection points is illustrated.
  • the name is arbitrary.
  • Significant voltage drops were measured here due to particularly large statistical fluctuations or due to an external influence such as a change in status, such as an increase in power demand, of another consumer in the electrical installation 3.
  • the significant voltage drop ⁇ U 2 (4) in itself indicates that the second connection point 30.2 and the fourth connection point 30.4 belong to a common safety circuit, which according to Fig. 3A would obviously be a misassignment.
  • This is avoided in the evaluation according to the present embodiment of the method according to the invention by first considering the voltage drop value with swapped indices, i.e. ⁇ U 4 (2). If really both connection points belong to the same fuse circuit and have a significant common line resistance, the voltage drop ⁇ U 4 (2) would have to be correlated with ⁇ U 2 (4), specifically a voltage drop of (approximately) the same size should be seen. However, this is not the case here: ⁇ U 4 (2) is well below the significance threshold ⁇ U min . The connection points 30.2 and 30.4 are therefore correctly assigned to different safety circuits after this first correlation test.
  • connection points to the same safety circuit
  • a significant common line resistance i.e. generating a significant mutual voltage drop.
  • a load test run in which several connection points are loaded at the same time. This can be done in the form of a second load test run after carrying out a first load test run with individual load tests of all connection points.
  • the first test run can also include time periods in which several connection points are tested at the same time. For example, simultaneous test time windows can be provided for all pairs of connection points.
  • connection point 30.1 to the same safety circuit as connection points 30.2 and 30.3.
  • the latter two connection points can be assigned to the same fuse circuit S2 based on the clear, significant mutual voltage drops.
  • FIG. 4D shown second load test schedule LTS2 in a time interval [0, T] a simultaneous load on the two connection points 30.2 and 30.3, or in general all connection points with which 30.1 could possibly be in a safety circuit, is provided.
  • a time window here [T, 2T] can also be provided, as is the case here in the LTS2 schedule in which all three connection points 30.1 -3, or in general all the load points in question, which could be in the same safety circuit, are loaded at the same time.
  • the LTS1a example load test schedule Figure 4A To see, in the time window [0, T] the two connection points 30.1 (on phase L1) and 30.5 (on phase L2), as well as in the time window [T, 2T] the two connection points 30.2 (on phase L1) and 30.6 (on phase L2) tested simultaneously.
  • the total duration of the stress test schedule LTS1 a the Fig. 4A is therefore 4T and is therefore advantageously a third shorter than the LTS1 load test schedule, which takes into account the same number of connection points Fig. 3A .
  • a voltage uncertainty ⁇ U can be defined and mutual voltage drops that fall within the interval [ ⁇ Umin - ⁇ U, ⁇ Umin] or [ ⁇ Umin - ⁇ U, ⁇ Umin + ⁇ U] or [ ⁇ Umin, ⁇ Umin + ⁇ U] are checked in a second load test run. More specifically, if for a pair, triple, etc.
